I rarely use sunscreen, but I use very good skin lotion containing retinol and collagen to make sure my skin is moisturized. That said, I have had 15-20 basal cell carcinomas over the last 40 years. The last four I had I cured using a baking soda/DMSO/Iodine/Hydrogen Peroxide mixture. I apply it to a Band Aid and let it work on the cancer overnight. It might take a few months to cure it, but it does work.
Referencing protection from the sun, I did have a few outside jobs in my teens and 20s but spent most of my career as an engineer in an inside environment. My brother, on the other hand, worked in the oil field for probably a decade in CO, WY, and NE. He never used sunscreen back then and probably worked 10-14 hours a day. Never had any skin cancer as far as I know.
I’m one who doesn’t use sunscreen. I’ll burn once when the weather warms up, then tan after that. Lots of outside work over the decades, including quite a bit in Arizona, and never any skin cancer. Of course, I do keep a pretty good eye on my numerous moles.
I have a different “home remedy” I have used.
I take grape seed extract, about 3,500 mg (3.5 grams), for a day or two.
The first time I did this, the whole thing peeled off 12 days later, like it was burnt skin peeling off.
It was completely healthy skin that replaced it.
I’ve done it twice over many years.
